    What is the greenhouse effect?

    Solar energy warms Earth, and greenhouse gases trap some heat.

    Why are greenhouse gases necessary, but too much is harmful?

    They maintain warmth for life, but excess leads to climate change.

    Why doesn’t all solar energy get absorbed by Earth?

    Some energy is reflected by clouds, snow, and light surfaces.

    What is albedo?

    It measures the reflectivity of a surface.

    Give an example of high and low albedo.

    Ice has high albedo; oceans have low albedo.

    What happens after Earth absorbs solar energy?

    It converts energy into heat and emits infrared radiation.

    How do greenhouse gases trap heat?

    They absorb and re-radiate infrared radiation.

    How does increasing greenhouse gases make climate hotter?

    More gases trap additional heat in the atmosphere.

    How is the greenhouse effect a positive feedback loop?

    Warming reduces albedo, leading to further warming.

    What are the main parts of a greenhouse effect diagram?

    Includes solar radiation, reflected radiation, and trapped heat.

    What is the difference between carbon sources and carbon sinks?

    Sources release CO₂; sinks absorb and store it.

    What are examples of carbon sources?

    Fossil fuels, respiration, wildfires, and deforestation.

    What are examples of carbon sinks?

    Oceans, forests, plants, and soil.

    How does carbon move between sources and sinks?

    Through processes like photosynthesis and combustion.

    How do humans impact the carbon cycle?

    They increase atmospheric CO₂ via fossil fuels and deforestation.

    Why must the carbon cycle stay balanced?

    A balanced cycle maintains a stable climate.

    What is reaction rate?

    It measures how quickly reactants convert to products.

    Why is reaction rate important for equilibrium?

    Equilibrium occurs when reactions happen at equal rates.

    What is collision theory?

    Reactions require particles to collide with sufficient energy.

    How does concentration affect reaction rate?

    Higher concentration increases collision frequency.

    How does temperature affect reaction rate?

    Higher temperature boosts particle movement and energy.

    How does particle size affect reaction rate?

    Smaller particles react faster due to greater surface area.
